3.5.0-p0 First 3.5.0 Stable release

This Version does only contain some minor new features and improvements.
But it has two incompatible Changes.

1. New Python Modules used as result of Security Updates.
2. Inventory Data has now a new prefix Style.

One can be resolved without much effort for the most of the users. But the second one
may need an update of your rules since the attribute naming for inventorized data is effected.
Not effected are rules which are based on attributes which are imported by normal plugins.

So please refer to the Documentation for this update:
